Technical Committee (TC) Intelligent Transport Systems (ITS) Activity Report 2021

Chair: Niels Peter Skov Andersen, Anemone Technology

Developing and maintaining standards, specifications and other deliverables to support the implementation of ITS Service provision for transport networks, vehicles and transport users, including interface aspects and multiple modes of transport and interoperability between systems.

Intelligent Transportation Systems (ITS) enable smarter, more coordinated, and efficient use of transport networks with the potential to increase safety for travellers and the public, minimize environmental impact and improve traffic management.

In ETSI our ITS Technical Committee (TC ITS) is developing global standards for Co-operative ITS (C-ITS), where vehicles exchange information with other road users and the surrounding infrastructure. Applications include road safety, traffic control, fleet management and location-based services, driver assistance, hazard warnings, support for emergency services – and ultimately the realization of fully autonomous driving.

Our standards relate to the overall communication architecture, management, and security aspects of C-ITS. As such they provide support for a wide range of services and applications. These include Cooperative Adaptive Cruise Control; Congestion Control; Cooperative Awareness, Perception and Manoeuvre Coordination; and Decentralized Environmental Notification (DEN) to alert road users. In addition, we develop conformance test specifications which are crucial for the commercial deployment of the technology and are closely involved in radio spectrum requirements for ITS.

In 2021 TC ITS published and updated various Technical Specifications and Technical Reports, namely:

In 2022 the committee’s Working Groups continue development of various deliverables, including:

  • ITS WG1 (Application requirements and services): Continuing work on CPS, and a Technical Specification for DENM Release 2.
  • ITS WG2 (Architecture and cross layers): Pre-standardization study on ITS architecture; Part 1: Architecture for communications among ITS stations with multiple access layer technologies); and an update of TR 102 962 (Framework for Public Mobile Networks in Cooperative ITS) to consider recent development of mobile network technologies.
  • ITS WG3 (Transport and network): specification of the Media-dependent functionalities for NR-V2X PC5.
  • ITS WG4 (Media and medium related): development of ITS-G5 (extension with IEEE 802.11bd) and LTE-V2X/NR-V2X (based on 3GPP Release 17) access layer specifications for Release 2.
  • ITS WG5 (Security): revision to TVRA; Misbehaviour Reporting Service (MRS); various test descriptions and conformance test specifications.

TC ITS continued to work in cooperation with ETSI TC RT on Road ITS and Urban Rail applications in the 5,9 GHz frequency band. The purpose of this work is to specify the solution to be applied in the ITS band (5 875-5 925 MHz) to meet Urban Rail ITS and road ITS applications requirements. These activities are linked to the COMMISSION IMPLEMENTING DECISION (EU) 2020/1426 on the harmonized use of radio spectrum in the 5 875-5 935 MHz frequency band for safety-related applications of ITS and repealing Decision 2008/671/EC.

During the year TC ITS maintained continual interaction with 3GPP regarding radio interfaces for V2X technology and its integration into the ITS architecture; as well as ongoing liaison with bodies including IEEE, ISO, CEN/CENELEC and the EC’s CONNECT, GROW and MOVE initiatives. The committee also remained in close contact with oneM2M, as well as ITU-T SG16 (Multimedia for ITS and Automated Driving), ITU-T SG20 (Internet of Things and its applications, including smart cities and communities) and FG-AI4AD (Focus Group on AI for autonomous and assisted driving).
